Task Order 10002a
Attachment A
Scope of Services
Odor Control Preliminary Design
Project Understanding
The City of Meridian would like to control odors from the Headworks at their wastewater
treatment plant. A meeting on Apri18, 2009 concluded that a building over the headworks is
desired, but the installation of future screens needs to be considered in the building layout.
Biofilters or Bioscrubbers are the preferred treatment equipment of choice, and further
refinement of the two technologies is needed. Additionally, odor control for the primary
clarifier sputter box needs to be considered as part of the odor control solution. Sampling of
the airspace around the sputter box and primary clarifier weirs to determine the extent of
odor generation is needed. A Preliminary Design Report summarizing the recommended
course of action for odor control facilities will be prepared and submitted to IDEA.
Scope of Work
CH2M HILL will perform the following tasks as part of this scope of work
Task 1-Project Management
Project management includes project scoping, staff management, task coordination,
monitoring project progress, preparing invoices, and ensuring project quality control..
Task 2 Treatment Technology Evaluations
Bioscnubbers and inorganic biofilters will be evaluated in detail including developing
preliminary layouts and providing detailed order of magnitude cost estimates. The results
of the analysis will be included in the Preliminary Engineering Report submitted to IDEQ.
Task 3-Building Evaluation
The feasibility of installing internally fed band screens into the existing channels in the
future will be reviewed. The results of the analysis will be included in the Preliminary
Engineering Report submitted to IDEQ.
Task 4-Primary Clarifier Sputter Box Odor Control Evaluation
Air sampling around the Primary Clarifier Sputter Box will be conducted to determine if
any odor problem exists. Ahand-held Jerome meter will be used to measure grab samples
of H25 at the Sputter Box. If objectionable levels of H2S are found, odor control measures
will be provided for the sputter box. The results of the analysis will be included in the
Preliminary Engineering Report submitted to IDEQ
Task 5 -Preliminary Engineering Report
An Engineering Report summarizing the preliminary design effort, will be prepared in
accordance with IDAPA 58.01.16, Wastewater Rules, and submitted to IDEQ. The
Engineering Report will include the following sections:
• Coordination With Existing Facilities
• Design Criteria
• Site Evaluation and Layout
• Process Units
• Instrumentation and Control System
• Regulatory and Code Review
• Cost Estimate
• Schedule
CH2MHILL will submit the draft report to the Owner for review. Review comments will be
incorporated and two copies will be submitted to IDEQ Boise Regional Office for review
and approval.
